Objective:To compare the diagnostic value of conventional fine needle aspiration biopsy(C-FNAB) and Ultrasound-guided FNAB(USFNAB) for thyroid nodules by Meta-analysis.Methods: PubMed and CNKI database were searched for English and Chinese language articles related to FNAB diagnosis for thyroid nodules.The literatures were assessed and screened according to the Standards for Reporting of Diagnostic Accuracy(STARD).Data were pooled by Metadisc software.Results: A total of 8 810 specimens were included in conventional FANA group and the pooled sensitivity,specificity,and the AUC of weighted summary receiver operating characteristic(SROC) curve were 84.9%,76.3% and 0.919 4,respectively;2 393 specimens were included in US-FNAB group and the above numbers were 84.0%,80.8% and 0.935 6,respectively.Conclusion: FNAB has high accuracy in diagnosing thyroid nodules;the accuracy of ultrasound-guided FNAB is higher than conventional FNAB.

OBJECTIVE: To investigate the protective effect of berberine on CCl4-induced acute liver injury in mice.METHODS: Kunming mice were included and equally divided into 6 groups: normal group,model group,berberine groups(40,20,10 mg?kg-1).After intragastric administration of corresponding drugs for 5 consecutive days,the mice were intraperitoneally injected with CCl4(10 mL?kg-1) to establish liver injury mice model.Alanine transaminase(ALT) and aspartate transaminase(AST) in serum,activities of superoxidase(SOD) and malondialdehyde(MDA) content in liver homogenate were measured.RESULTS: In Berberine-treated groups compared the model group,serum ALT level and AST activity decreased significantly(P

Objective To compare the therapeutic effects of three operative procedures,removal of armpit skin,minimally-invasive aspiration and small transverse incision in the treatment of osmidrosis.Methods Retrospective review was conducted in the treatment of osmidrosis for near ten years.Three methods were compared in the indication,feature and effectiveness.Results A total of 459 cases (123 males and 336 females) of osmidrosis were treated with the three methods.Satisfactory rates of the three methods were 98%,96% and 97%.respectively.Recurrence was found in 7 cases.Conclusions Modified procedure of minimally invasive aspiration has advantages of quick recovery,less complications and satisfactory results.It is the first choice for patients with mild and moderate osmidrosis.Bat for male patients with severe or recurred osmidrosis,treatments are surgical removal of the skin with armpit hairs and suture method.

Objective To evaluate the value of transcatheter arterial embolization(TAE) in the treatment of intractable epistaxis.Methods TAE using gelform or polyvinyl alcohol(PVA) particles of forty-one patients with intractable epistaxis were undertaken by the femoral artery approach,through selective catheterization of involved maxillary artery or the bleeding arteries for the stopage of bleeding..Results Of the forty-one patient,39 cases were cured by once TAE and the other 2 with recurrent bleeding on the next day after the TAE,to whom a second interventional treatment fullfilled the requirement.Conclusions Transcatheter arterial embolization is a simple,safe and effective treatment for the intractable epistaxis.

ObjectiveTo investigate the protective role of Lazaroid U 74389G pretreatment against graft warm ischemia reperfusion injury of rat liver transplantation from non heart beating donors.MethodsRat liver transplantation was carried out in 4 groups (N 45, N 60, tN 45 and tN 60), according to pretreatment with U 74389 G or not, and the non heart beating time of 45 or 60 minutes before donor liver was harvested.Survival rates, liver functions, MDA values and graft pathologies were compared between the groups.ResultsThe one week survival rates of group N 45, N 60, tN 45 and tN 60 were 25%(2/8), 0(0/8), 58%(7/12) and 33%(4/12) respectively.U 74389G pretreatment not only significantly increased survival rate of rat liver transplantation from non heart beating donors, but also improved liver functions and graft pathologies, as well as decreased MDA expression.Conclusions U 74389G pretreatment could attenuate ischemia reperfusion injury on donor livers and increase the survival rates in rat liver transplantation from non heart beating donors.

The writer's college cultivated students' scientific research ability through the extracurricular society of undergraduates-matrix clinic quality team(MCQ).The writer's colleges promoted studnets' academic ability and expanded the impact of the school by strengthening scientific research basis and preparation,making students familiar with the process and making students experience and participate in international academic exchanges.

Objective To explore the effect of situational clinical probation fourth-step method in Nursing Managementteaching in clinic.Methods We introduced innovative teaching method in clinicsituational clinical probation fourth-step method in Nursing Management.Firstly,it took students to learn the construction of the management structure in clinic (observation),then interview management persons (interview),and playing roles in management activities (role-play),at last interactive discussion (seminar).Results Through the SCP fourth-step learning,the nursing students' learning ability was strengthened,the students' ability to innovate and the learning interest in nursing management were inspired.Conclusions Application of situational clinical probation fourth-step method in Nursing Managementteaching in clinic shows better effect,which should be widely applied in clinic practice.

Objective To investigate the relationship between cancer-related fatigue (CRF) and quality of life (QOL) of the colorectal cancer patients.Methods In this study,patients diagnosed definitely as colorectal cancer were enrolled from November 2010 to January 2011 in this hospital.Piper Fatigue Scale was used to assess the CRF and QLQ-C30 was used to assess the QOL.Results 74 patients were enrolled in this study,and among them 28 patients had CRF(37.84％).Patients with CRF was significantly worse in QOL than patients without CRF.Physical function,role function,emotional function,social function and the general health subscale had a negative correlation with CRF,while pain,fatigue and loss of appetite had a positive correlation with it.Conclusions CRF had an impact on QOL,and this study will provide some reference information when the nurses take measures to intervene CRF and improve QOL of the colorectal cancer patients.
